Understanding Heavy &...

When enquiring about adaptors or hose ends with metric thread, we here at Gerrard Hydraulics will always ask if the thread is metric heavy, metric light or screwing into a port or manifold. The latter will be discussed later but first, we’ll take a look at what metric heavy and light are all about. Metric hydraulic fittings come in a range of standardized thread sizes. These thread sizes are usually available in both a heavy and light series. The heavy series is for a smaller tube OD with a thicker wall. The light series for...

DIY Repairs &...

Think twice before repairing and installing your own hydraulic equipment. Many people think that they can repair and install their own hydraulic equipment. However, it does not always turn out the way they plan. They believe they can save a buck or two by trying to do it themselves. For instance, the above hydraulic motor was leaking, so the owner decided to repair it himself by welding it up to stop the leak. If he had proper training and understanding of hydraulic components, he would know welding on a cast iron housing...

Hydraulic Pumps: How It Works

Hydraulic Pump A hydraulic pump converts mechanical energy into hydraulic energy. When a hydraulic pump operates, it performs two functions. First, its mechanical action creates a vacuum at the pump inlet which allows atmospheric pressure to force liquid from the reservoir into the inlet line to the pump. Second, its mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system. A pump produces liquid movement or flow: it does not generate pressure. It produces the flow necessary for the...

Everything You Need to Know...

Hydraulic motors are one of many mechanical components that make your machinery work the way it's supposed to. Here, we look at what hydraulic motors are, and why they're important. What are Hydraulic Motors?  A hydraulic motor converts hydraulic energy into mechanical energy; a rotating shaft. It uses hydraulic pressure and flows to generate the required torque and rotation. You can use hydraulic motors for many applications, such as winches, crane drives, self-propelled farming equipment, excavators, mixer and agitator drives,...

Why Phasing Cylinders are...

It’s that time of year again when farmers are busy planting the seeds for their crops, using purpose-built machinery. Since a successful crop production is dependant on the seeding process, ensuring your site is properly prepared, and you’re using the best possible hydraulic machinery for planting your seeds, is a must! What's the Seeding Process? Seeding, as the name suggests, is when farmers plant the seeds that will ultimately grow their crops. This process could be completed by hand if you’re only working with a...

Why You Should Get Extra...

We often get enquiries in regards to adding an extra set of remotes on the back of tractors for easy cross over from one hydraulic circuit to another. For example, you have a tractor with only two sets of remotes and you are towing your air seeder that has 3 functions (2 wing lifts and a main lift). With the 6 port diverter fitted to one remote set you now have a 3 remote outlet. Now you simply connect the solenoid to an electrical switch in the cab and by turning the selector on/off you can operate two functions from the one...

What are Quick Release...

In hydraulic fluid power systems, power is transmitted through an enclosed circuit via fluid under pressure. Quick release couplings or QRC’s (also known as quick-action couplings, quick connect couplings, break-away couplings, just to name a few) are used to join or separate fluid conductors to or from a circuit. There are just as many types of QRC’s as there are manufacturers. Thankfully, there is an international standard to which the manufacturers conform to. The International Organization for Standardization (ISO)...

How to Diagnose a Faulty...

Do you have a creeping bar and think a phasing cylinder might be at fault? How do you determine which cylinder, if any, is the faulty one? Unfortunately, diagnosing a faulty phasing cylinder isn't always as simple as identifying the moving cylinder. Why? Because the moving cylinder isn't always the culprit. Below is a handy diagnostic chart that shows, while under load, the interaction between good cylinders and faulty ones. Need help identifying the condition of your phasing cylinders? Or maybe you just need...
